I've removed the curled lower leaves from the plant and have sprayed it with Safer insecticidal soap. It's gained some height and a bit of bulk now that sunny warm weather has returned to the area but because of the plant's overall stunted growth I probably won't top or prune it.
Two other habanero plants as well as a big bertha bell have been topped and are showing thick branching growth after two weeks. Awesome.
But the seedlings I bought at a plant show nearly a month ago (Ghost, Fatalli, Caribbean Red Hab, Peter Pepper) are continuing to show slow growth, poor root development (discovered this during transplanting to larger containers), and are not tolerant of being put out in the sun for very long. One of the Ghost Pepper plants got scalded lower leaves. I think the root problem is related to being overwatered. Now growing in much larger containers hopefully this problem with take care of itself. I'll leave them in indirect light for a few more weeks.
